MANIFOLDING DEVICE Filed Sept. 3, 1926 '7 Sheets-Sheet '7 Patented Apr. i2? QE GUSTVE G. DEGENER, 0F BROOKLYN, NEVII YORK, ASSIGNOR T0 ROYAL TYPEWRITER COMPANY, INC, GF NEW-YORK, NY., A CORPORATEON 0F NEW YORK MNEFOLDING DEVICE Application filed September 3, 1926 Serial No. 133,437(

This invention relates to an improved construction which may be attached to the carriage of any standard typewriting machine without much modification in the machine itself, and is designed for the purpose of writing on continuous billing forms which are frequently fedito the machine in lengths of several hundred feet. y

The invention primarily has for its object to provide a new and improved manifolding device in the character of an interfold billing machine adapted for writing upon superposed continuous work sheets or webs of con-- neeted forms and wherein is provided means to feedjor line space the webs past a platen and over a frame on which said webs are so positioned as to provide for complete visibility, thereby greatly' facilitating the writing operation and reducing to the minimum the possibility of error, and for feeding narrow carbon strips interleaved with the webs across the printing line and which after being so fed may be torn o and thrown away, the use of carbon strips insuring uniformly inked carbons at all times and eliminating the great waste of time and material and other disadvantages incident to the use of carbon sheets.

Another object of the invention is to provide means separate from the platen to effeet linespacemovements to the superposed work sheets. said means including a clamp which securely grips the leading ends of the work sheets to thereby maintain the super# posed forms of the work sheetsy in registration during the entire time said work sheets are fed through the machine.

Another object of my invention is to provide means for positioning the webs and carbon strips in tight Contact relation against the curved printing line of the platen preparatory to certain printing operations wherebyclear impressions will be made on the various webs, and to relieve the tight contact relation between' the webs and lcarbon strips, and the platen, prior to feeding or line spacing movements of the webs whereby said webs will be disposed in a substantially iiatl The invention herein claimed includes means for feeding these forms or work sheets upwardly past a guide, thence past the platen,

land thence upwardly over a frame which extends upwardly from the jdelivery side of the platen.

Another object of the invention is to construct and mount the frame over which the webs are fed so that said frame may be swung between rearwardly -inclined and substantially vertical positions, and to provide means to so ho-ld and guide the webs that when the frame is in the inclined position the written portions of the webs will be presented to full view of the operator and in substantially r1ght angular relation to her line of vision, and whereby the web sheets and carbon strips will be compacted tightly against the printing line of the platen and form a close pack so that the impact of the type bars will carry through to the last copy with alight staccato blow and thus insure uniformly sharp, clear l carbon copies, and when the frame is moved to the vertical position,'the webs willfbe disposed substantially at and the prior compacted condition of the web sheets will .be relieved to facilitate line spacing of the webs without dragging the interleaved carbon strips or smutting the web sheets by dragging over the carbon strips while in tight relation.

Another object of the invention is to provide means whereby the swinging or moving of the frame is eected by mechanism controlled by the same lever that .effects line spacing of the webs, and feed of the carbon strips, and to so time the operation of these devices that the line spacing operation and strip feed operation are effected while the frame is in the vertical position only.

Another object of the invention is to provide novel means to feed the carbon strips, including means to adjust the degree of feed.

Another object of the invention is to provide means to impose a tension on the carbon .strips whichis active at intervals only to prevent carbon strip movement with the webs in a direction transverse to the direction of carbon strip feed.

Another object of the invention is to provide means to impose a constant tension on said spools.

Another object of the invention is to provide a novel line Aspacing means which includes a truck movably mounted on the swingable frame and having a clamp thereon to receive and hold the leading ends of the work sheets, and means to move the truck upwardly step-by-step to effect line spacing of the work sheets.

The invention also comprehends means whereby the truck may be released after each form has been completely written from clamping engagement with the work sheets and from the line space movement effecting means, so that said -truck may be lowered or returned to its starting position after which the clamp is caused to grip the next form preparatory to line spacing thereof, the clamp eing utilized as a straight edge when tearing off the completed form.

Another object ofthe invention is to mount the platen directly on the' frame and to'provide novel means for swinging the frame to impart thereto a Hoating pivotal movement whereby the upper and lower ends of the frame will be caused to move reversely, that is, one end moves forwardly as the other end moves rearwardly and vice versa, to thereby cause the platen to engage and tightly compact Ythe work sheets in curved condition at the printing line of the. platen during printing intervals, and to move the platen to relieve the compacting contact and also to dispose the work sheets substantially fiat and vertical during line spacing intervals.

The invention is illustrated as applied to the well known standard Royal machine which employs the usual inking ribbon, but as will be obvious it is capable of application to other types of machines. 'lt is also not limited to a typewriting machine but may be applied to a combined typewriting and computing machine or other machines of this general character. Certain features of the invention are not limited to a machine in which work sheets travel in letter space direction relatively to the type', but may be embodied in a machine in which the type travels relatively to the work sheet for letter spacing or in which there may be no letter spacing movement at all.

Further detail features of the invention will be apparent from the following description and the appended claims.

5 Figures 20, 21 and 22 are fragmentaryl plan views illustrating the parts shown in Figure 11, and diagrammatically illustrate' the respective ositions of the control lever in the course o moving the frame to the vertical position and for applying the additional tension to the carbon strips, the posi tion at which the yframe is fully swung to the vertical position and the additional resistance fully applied to the carbon strips, and

ance has been released and the line spacing mechanism and the carbon strip Vfeed about to be actuated, the frame being held in the vertical position at this time.

As previously stated, the invention may be embodied in various types of typewriting and analogous machines and there has accordingly been illustrated only enough of. the usual typewriting machine to showl the position of the mechanism comprising this invention with relation thereto. The drawings illustrate a main frame A, a carriage having side plates B, the carriage having a rail C which is adapted to travel upon a main rail D by means of interposed ball bearings. A type bar E is illustrated in the positionwhich it occupies just prior to printing. The tabular stop rod F is carried'by the side plates B of the carriagev and is of the usual con! struction. The paper table G is or may be of the usual construction and the work sheets H are fed thereover to the platen.

The usual platen is removed, but the platen shaft or axle l is retained and is 'ournalled in the side plates of the carriage. elow this the shaft 2 is also attached by screws 3 tothe side plates, and a chute 4 is fastened to blocks 5 which arecarried onf the shaft 2. At each side of the machine and just inside the-blocks 4 is an arm 6. At the right hand side of the machine the arm 6 is pivoted at 7 to an inverted U-shaped or channel-shaped member 8 and at the left hand side of the machine, the

arm 6 is similarly pivoted to a similar channel at their top by screws 11 to a rod 10. The arms 6. side members 8 and'9, and/ rod 10, therefore, constitute a frame andsince the members 8 and 9 are pivoted to the arms 6, it is `obvious that the frame may be swung about this pivot point. The outside flange of each channel member 8 and 9 has an extension 12 clearly shown lin Figure 6 provided with an arc-shaped slot 13 which engages the platen axle 1. A platen 14 which is preferably formedof brass or similar metal, is attached by screws 15 to the channel members 8 and 9.

As shown in Figure 6, the work sheets H are i fed over the paper table G to the chute 4 and T5 thence upwardly over the platen 14 and lie the position at ywhich the additional resist- L ing ends of the work sheets thereto. 'truck or holder Y is normally located at the member 9. These two members are connectedv .upon the frame at the delivery side of the machine. v

The same screws 11 which attach the rod 10 tothe side bars of the frame also fasten to said frame the upper ends of links 16 which are pivoted at their lower ends at 17 to links 18 mounted on a rockshaft 19 extending from one side tothe other of the work sheet supporting frame. Each link 16 has an ollset lug 2O adapted to engage the link 18 when the parts are in the operated or full line position of Figure 6. The shaft 19 has a downwardly extending arm 21, the purpose of which will be'hereinafter set forth.

From the. foregoing it will be observed that the frame X is pivoted at its lower end to swing rearwardly to a rearwardly inclined position and forwardly to a substantially vertical position, and that the platen 14 is xed to the lower end of the frame to move therewith whereby the platenwill be bodily asv moved rearwardly when the frame is swung forwardly and moved forwardly to its origiwardly.

Supported on the frame X for movements toward and from the platen is a truck or holder Y having means for clamping the lead- This lower end of the frame X and means is provided for moving the truck or holder Y upwardly along the frame ina step-by-step manner to impart line spacing movements to the work sheets. This line spacingmechanism is operable when the frame X is in its forward or vertical position.

Thus prior to the line spacing operation of the'work sheets, the platen'has been moved 'rearwardly' a distance sufficient to relieve the tight contact relation between the work sheets and the curved printing face of the platen 14. In other words, when-the frame X is in its vertical position, the work sheets are substantially free of contact with thev platen and consequently these work sheets may be line spaced without dragging the same against the platen and without dragging the transversely extending carbon strips vupwardly therewith. lVhen the frame X is in its rearwardly inclined position, the type bars are operated. In this position of the frame X, the work sheetsand carbon strips are caused to tightly contact the curved printingface of the platen 14 whereby the work sheets and the carbon strips will be disposed in a compacted relation to insure clearness of print on the various sheets. Thus in one position, the work sheets are arranged in substantially flat relation for line spacing operation, and in another position thesel work sheets are curved about the curved printing face of the platen preparatory to printingby the type bars.

The truck or holder Y includes at plate 22 Less which is positioned on the upper side of the members 8 and 9 and has downward extensions 23 and 24 respectively fitting on the outside of these channel members. This plate 22 constitutes a relatively stationary clamp` bar and is provided on its under side (see *igure 7) with two brackets 25 and 26 in the depending arms of which is supported a shaft 27 which has at one end a pinion 28 meshing with a rack bar 29 on the inside of the channel bar 8. At the other end the shaft27 has a pinion 30 meshing with a similar rack bar 31 carried by the channel member 9. The purpose of the shaft and rack and pinion connections is to cause the truck Y to travel along the channel bars 8 and 9 of the frame X without binding.

Lyinr outside the extensions 23 and 24 and attached thereto in any desired manner, are plates 32 and 33 respectively which extend upward above the surface of theplate 22. These plates are connected by a pivot shaft 34 attached thereto by screws 35 and this shaft carries a clamp member or movable clamp bar 36. The work sheets are adapted to be passed between this clamp member or bar 36 and the surface of the relatively sta- I tionary clamp har 22.

` 38 by means of a spring 39 which is fastened at one end to the lever arm 37 and hooked at the other end over a projection 40. The rod 38 is provided with cam portions (see Figure 19) which' bear a ainst the arms 37 and this rod may be rocke affainst the tension of the spring 39 by means of handles 41. lVhen thus rocked, it will move the clamping plate 36 away from the surface of vthe plate 22 and release the Work sheets so that the truck Y and work sheets may be moved independ entl Ai, the left hand side of the frame X the outside flange 42 of the channel bar 9 is provided with teeth or notches lin which is adapted to engage a pawl- 43 pivotally supported at 44 and normally drawn to operative position by a spring 545. This pawl has an upwardly extending tail 46. A similar pawl 47 `is carried by the same pivot 44 and engages notches formed in a bar 48 illustrated separately in Figure 12. The function of A this bar will be hereinafter described. This lever arm 37 to release the truck Y, it is obvious that thejmovement of this lever arm 37 will produce a sliding movement of the plate 50 through engagement with the ear 52 thereof and that in such sliding movement the ear 53 will engage the tails of the pawls 43 and 47 andv move them out of operative engagement with their respective racks or notched bars. In this manner the movement of the lever not only releases the truck Y from the work sheets but releases the truck from the frame so that it may be moved downward until j it substantially contacts with the laten 14.

In the orm of the device shown in Figure 6 kthe work sheets H are fed over the rock shaft 19 from the desired source of supply. In the preferred form of the invention shown lin Figures 1 to 4, a different form vof feeding the work sheets is provided. y

Arms 54 which are attached to the frame of the machine by the same screws which hold the feet I in position extend rearwardly and otherl bracket arms 55' which are attached to the top-plate of the machine by screws 56 extending downwardly so that the free end of each arm 54 will lie adjacent the free end of the corresponding arm 55. Screws 57 attach each pair of armsl together and also are threaded into a track rail 58, thus supportingthe same.

A roller 59 which travels on said track rail is carried by a U-shaped bracket member 60 which is attached by a screw 61 to the generally horizontal portion 62 of a U-shaped member. The upwardly extending arms 63 of this member are pivoted by screws 64 to downwardly extending arms 65 which depend from theV plate member 66 (see Figure 2). This plate supports at its outer ed es channel shaped members 67, the open sides of which face each other and these members are provided at their upper ends with hook members 68whieh engage the under side of the shaft 19. The channel members 67 and the chute 4 individually and together form n side edge guides for the webs and aid in holding the work sheets or forms in registration. At each side a spring 69 is attached at one end to an anchorage 70 on the member 67 and at its other end is hooked over an upward projection 71 of the arm 63. It is obvious that this spring exerts its force to hold the hook 68 in contact with the shaft 19 and the roller 59 inA engagement with the track rail 58. Projections 72 on the lower end of the arms 65 limit the movement of the arms 65 and 63 in one direction. l

The application also discloses two different (forms of mechanism for supporting the carbon strips or ribbons, the preferred form being illustrated in Figures 1, 3 and 4. In this form a spindle 73 which may be an extension of the spindle which -fastens the hell stem in place has mounted thereon a plurality ,Letasoa of rolls of carbon strips or ribbon K. These rolls are separated by disks 74 provided with key hole slots by which they may bel readily mounted upon the spindle 7 3.

At the left hand side of the carriage a channel shaped member 75, which opens outwardly, is attached to the -side bar of the carriage by a screw 76. To the under side of this channel bar is attached an inwardly extending bracket 77 which is provided with a plurality of vertical pins 78 and each strip K is fed between af' pair of said pins. Overlying the upper side of the channel bar 75 1s an inwardly extending member 79 which is divided at its inner end into a plurality of spring tongues 80, each of which engages a corresponding carbon strip. The bracket members 77 and 79 may be connected to the channel bar 75 by bolts 82 provided with iinger nuts 83. Pins 81 extend between the two sides of the channel bar and furnish guides for the various carbon strips. Reference to Figure 4 will show that after each carbon strip K passes from beneath a spring tongue 80, it is given a quarter turn so that it occupies a vertical plane and passes around its appropriate pin 81'. Itis then lead toward the front side of the machine and fed by mechanism vwhich ishereinafter described.

Another form for supporting the rolls of carbon strips-and placing initial and constant tension thereon is shown particularly in Figure 9. In this construction two brackets 84 attached to the side frames of the carriage support a plate 85 upon which are mounted spindles 86 on which are placed the rolls of carbon. These spindles occupy a vertical position so that the carbon does not need to be given a quarter turn as in the preceding form. After being drawn' offrom the roll, each strip Kpasses over a stationary friction pin 88. As shown in Figures 15 and 16, this pin cooperates with a second pin 89 carried by a plate 90 which is provided withl an opening 91 through which passes the shank of a shoulder bolt 92 which supports the plate in position but permits sliding movement thereof. Each pin 88 is carried by a plate 87 which has its rear end passed through a receiving slot in the rear turned-down flange of the plate 85 and its forward end secured to the l-plate 85 by a single shoulder bolt 92. A

spring 93,-connected to the plate 90 at one end and to a fixed part at the other end, normally tends to bring the pin 89 into frictional Y engagement with the pin 88, the carbon strip K passing between the two. This mechanism is provided in connection with each carbon strip and each plate has an offset ear .94 adjacent which passes a rod 95 provided with cam surfaces 96 for operating the same and corresponding in number to the maximum number of ribbons which can be employed. This rod may be operated from either side of the machine by means of handles 97 so bon strips, for guiding them across the front of the machine and for feeding them lengthwise step-by-step is the samein both forms of the carbon strip supporting means and will now be described with particular reference to Figures 9, 13, 14, and 17.

Afterthe carbon strips pass the guide roller l 98 of lFigure 9 or the guide pins 81 of Figure 4, they pass through mechanism which is adapted for imposing additional frictional resistance thereupon as desired. A channel bar 99 is fastened to the side plates vB of the 'carriage by a pin 100, but is spaced therefrom by a spacing block 101. Mounted within the channell is a spring 102 which is fastened to the bottom of the channel bar by a screw 103 and is bent on itself so that its free end will bear against a projectingportion 104.' Carbon strips K pass between the projection 104 and the free end of the spring 102. A cam-mem-` ber 105 is mounted on a pivot 106 and is carried by a lever 107 which is pivoted at 108 to a link 109. When this link is operated as hereinafter described, the cam 105 will be turned to contact the springv 102 and press the free end of said spring against the carbon strips, thus imposing additional resistance thereon.

This'additional resistance is not intended to be very great and is only imposed at certain times as hereinafter described, and in some respects a modified form of this portion of the mechanism shown in Figure 10 is found preferable. In this modified construction instead of the spring 102 there is provided a springA 110 attached to the channel bar by a screw 111 and having a free end 112. This spring is bowed slightly intermediate its ends and the bent portion is intended to press the carbon strip K against the projection 104. The lever 107 together with the cam 105 is the vsame as in the other form, but instead of the link 109 one end of a. coil spring 113 is attached to the lever 107, the other end of the spring being attached to an operating mech-- anism which will now be described. The

channel bar 116 is fastened to the side plates B of the carriage by a screw 117, a spacing block 118 being interposed to space the two parts.I The carbon strips K now pass be-V tween two corrugated'rollers or gears 119 and 120. The gear or roller 119 is the feeding member and is given its motion by a detent 121 normally held in engagement with the roller by a spring 122. A holding detent 123 is also'norma-lly held by a spring 124 in contact with the roller 119 to prevent reverse movement of the same. The feeding detent 121 is carried by a forwardly extending link 125 which is given its feeding movement by means hereinafter described.

It is desirable that the rollers 119 and 120. be pressed against each other with considerable force and also that they may be separated for the purpose of feeding in fresh carbon strips. To attain this result the following construction is employed. As clearly shown in Figure 17, the roller 119 is pivotally` mounted in the sides of theL channel bar 116. The roller 120 ismounted on a spindle 126 provided with a linger piece 126 and this spindle is mounted in the sides of a U-shaped frame'127 which fits over the channel bar 116. A rod having a cam 128 thereon is mounted in the U-shaped frame 127 and is provided with a handle 129. Whenl this rod is turnedthe cam engages a bracket 130 which is fixed to the channel bar `116 as clearly shown in Figure 13, and therefore moves the whole U-shaped frame toward the right in Figures 13 and 17, thereby moving the roller 120 out of engagement with the roller 119. This movement is in opposition to a fiat spring 131 which is fastened to the side frame B of the carriage by a screw 132 and is attached to the U- shaped frame 127 by fastening means 133 and normally tends to move this frame toward the left in Figures 13 and 17. The U-shaped frame is guided in its slidingr movement by lugs 134 and 135 ixed to the channel bar 116.

As stated above, astep-by-step movement of the truck or holder relative te the frame X, for the purpose of giving line space movement to the work sheets, brought about by moving the notched bar 48. This bar has lugs 136 at each side thereof, the lugs on one side contacting with the rack bar 31, and the lugs on the side with theoutside wall of the channel bar 9 as shown. 1n Figure 7. These lugs guide the notched bar in itsl to and fro movement. The free end thereof is provided with a notch 137 which fits over a pin (not shown) extending between the walls of the channel bar y9. A spring 138 is attached at one end to the bar 48 and at its other end to a fixed part 139 and serves to return the bar after the upward movement thereof.` To the lower end of the bar 48 a Shorttrack 140 is pivoted at 141 and is normally maintained in one position by a spring 142 attached off centerl to the rack at one end and at its other. end to the bar 48. This rackv 140 meshes with a pinion 143 carried on one end of a short sleeve 144Which is loosely mounted on the platen shaft 1. Itis-ill be obvious that when the pinion 143 is rotated, it will give an upward movement to the bar 48 and the engagement of the notches of this bar 48 with the pawl 47 will move the truck or holder Y-upward one line space distance. The truck will then be retained in its new position by the pawl 43 and the spring 138 will act to return the notched bar 48 to its starting point.

The link 125 which, as explainedl above, is moved for the purpose of feeding the ribbons, is connected at its free end to one arm of a bell crank lever 145 which is pivoted at 146 to the channel bar 116. The other arm of this bell crank is provided with a slot 147 in which may be adjusted a pin 148 which is carried by a small U-shaped member 149. A link 150 is connected to the pin 148 and it is obvious that an adjustment of this pin in the slot toward and from the pivot 146 of the bell crank lever will vary the amount of movement given to the link 125 and, therefore, the extent of feeding movement of the yribbon Aor carbon strips.. This link 150 extends to the left hand side of the machine and is connected to one arm 151 of`a bell crank lever pivoted at 152 to a bracket arm 153 extending from the carriage frame. 154 of this bell crank lever is pivoted at 155 to a link 156 which is provided at one side with a short rack 157 which meshes with a pinion 158 on the sleeve 144 above mentioned.

The arm 21 best shown in Figure 6, which extends from the rock shaft 19, is pivoted at its free end at 159 to a forwardly extending link 160. When this link is moved rearwardly, the arm 21 rocks the shaft 194 and moves the arms 18 and 16 as well as the frame to the dottedA line position of Figure 6, in which the sheet supporting frame is substantially vertical. At the same time the pivot point 7 of the frame and the arm 6 moves slightly to the rear, being guided by engagement of the slot 13 with the platen axle 1 so that the platen moves slightly away from the work sheets H. The relative position of the los The other arm l upon the carbon strips. A rearward movement of the link 160 will move the frame supporting the work sheets from the full Yto the dottedf line position of Figure 6. A rearward movement of the link 1,56 will rotate the pinion 158 and sleeve 144, thereby rotating Lthe pinion 143 and line spacing the work sheets. At the same time this rearward movement of the link 156 through the bell crank lever and connection 150 to the opposite side of the machine will feed the ribbons a short distance lengthwise. The construction by which'these various operations are performed in the proper sequence will now be described.

`This operating mechanism will be de-- scribed with special reference to Figures, 9, 11, and 18. Aflat cam member 161 is pivotally supported at 162 upon abracket 163 extending from one side bar of the carriage. Fastened to the cam 161 by a screw 164 is a lever 165 which corresponds in general location and shape to the usual carriage return lever of a typewriting machine. Three levers 166, 167,V and 168, shown separately in Figure '18, are pivoted at 169 upon an extension of the bracket 163. This pivot pin 169 passes through an opening 170 in one end of the lever 166, an opening 171 in one end of the lever 167, and an opening 172 inthe lever 168 which is a bell crank lever. One arm 173 of this bell crank lever has a roller 174 which normally engages the portion 175 of the cam 161. When the lever 165 is operated by movement to the right andthe cam 161 rotated, the first movement thereof rocks the bell crank 168 and pulls on the link y109 or the spring connection 113,l in Figure 10,

177 of the bell crank lever 168 at 178. This pull will impose the additional frictional resistance upon the carbon strips or ribbon;

During movement of the lever 165 to the right a cam portion 179 which' is in engage-` ment with a roller 180 carried by the lever 166, will swing this lever rearwardly and since the outer end thereof is connected at 181 to the link 160. this movement will swing the frame forwardly from its normal rearwardly inclined positionto the substantially vertical 'or dotted line position of Figure 6.' At this time the cani 161 is in the full line position of Figures 9 and 21 and the lever 166 is in the dotted line position of said Figure 9 in full line position in Figure 21.

A continued movement of the lever 165 in the same direction will cause the roller 174 to move down the surface 182 of the ycam 161 and release the additional frictional resistance which has been placed upon the carbon strips or ribbons. During this' continued movement, the roller 180 rides on the surface 183 of the cam which is concentric with the pivotal center thereof and, therefore, the frame is held in its vertical position.

. Shortly after the cam passes from the position shown in Figures 9 and 21, a roller 184 carried by the under side of the cam 161 will move in the direction shown by the arrows in vsaid figure and engage the lever 167 as shown in Figure 22. This lever is pivoted at 185 to the link 156 and the movement of this lever will, therefore, through the rack 157, pinion 158, sleeve 144, and pinion 143, operate to line space` the truck Y. During this period of line spacing, the roller 180 engages the con` centric peripheral portion 183 of the cam 161, to maintain the frame X in its vertical position. At the same time the movement of the link 156 through the bell crank 154 and connections will operate to 'give the carbon, strips or ribbons a short endwise or feeding movement.

Immediately following these operations the carriage will be returned to the right hand side of the machine and uponreturn of the lever to its initial 'position the work sheets will be in position to begin a new line Aof writing.

In loading the machine with the work ksheets and carbon strips preparatory to writthe shaft 19, then downwardly and forwardly over the table G, thence upwardly through the guide chute 4 to a point somewhat above the printing line across the platen 14. The

'members 67 and the chute 4 constitute side which link or spring is connected to the arm about the guide roller 98 and threaded through the additional tension applying devices 102, 104, after which said ends are drawn forwardly and turned about the guide Y roller 114 at the front left hand corner of the machine. At this time the frame X is in its normal rearwardly 'inclined position and the additional tension device 102, 104 is in its normal or 'ineffective position.

T he free en ds of the carbon strips are pulled forwardly a sullicient distance and are next `interleaved with the leading ends of the superposed work sheets comprising the form web and which portions extend above the chute 4, one carbon strip being placed be tween each adjacent pair of such sheets. The free ends of the carbon strips are then turned -about the guide roller 115 at the right hand front corner of the machine and thence rearlation of the cam lever 129 yand which are thereafter released to cause them to opertively engage the carbon strip ends between them.

` By moving the lever `v165 from the osition shown in Figure 11 to the position s own in Figures 9 and 21, the frame will be moved to the substantially vertical position shown in dotted lines in Figure 6 andfor causing the devices 102, 104 to grip the carbon strips for the purpose of applying additional tension thereto for the purpose of holding said carbon strips taut across the printing line.

At .this time the truck Y will be supported upon the frame X a suitable distance above the leading ends of the work sheets. The operator may now rasp the work sheets at their leading ends a ove and free of the carbon strips and pull them upwardly toward the truck. The carbon strips being taut by reason of the application of additional tension `devices 102, 104, will be held against any tendency of being dragged upwardly with the work sheets during this period, and in view of the flat relation of the work sheets and the substantially vertical direction of pull, all frictional engagement between work sheets and carbon sheets, that would tend to smut or smear said work sheets is effectively avoided.

Vhile'holding the leading end of the web in her grasp, the operator actuates the lever 41 of the truck to release said truck from connection with the line spacing mechanism, and to separate the stationary and' movable clamlping members 22 and 36 of the truck. T e truck thus released may be conveniently supported upon the hands of the operator while the leading end of the web is moved upwardly by the operator through and a suitable distance beyond the clamping members 22 and 36 where the vweb will be again grasped by the operator after which the truck is freely lowered to its lowermost or starting position. The web is then adjusted longitudinally so that the clamping member 36 will engage the web at the line dividing the first and second `forms of the web, after which the lever 41 is moved to cause the clamping member 36 to securely clamp the web against the member 22. The form above the truck is negligible waste and may be torn ofi", using the clamping member 36 as a straight edge for that purpose. The first form is now in position wherein the first line thereof is in 'registration with the printing line of the platen.

The lever 165 is then returned to its initial position as shown in Figure 11, the additional tension on the carbon strips belng released and the frame X being returned to its normal rearwardly inclined osition as shown in full lines in Figure 6. he work sheets and interleaved carbon strips will, by this return movement of the frame, be changed from their previous vertical flat and loose condition to an arcuate and tightly compacted condition in engagement with the platen at the printing line. The machine is now ready for writing operations.

The first line will then be written on the form in the `usual manner. It then becomes necessary to line space thework sheets so that the next succeeding line of the first form ma bbewritten.

o this end the operator swings the lever 165 forwardly and toward theright. The first part of this movement will cause the appropriate surfaces o'f the cam 161 (see Figure 20) to engage the rollers 174 and 180 to .impart a pull on the link 109 and a thrust on the link 160 to impose the additional tension upon thecarbon strips and to swing the fra-me X forwardly to the vertical position respectivel Thus when the lever 165 has been move to the position shown in Figures 9 and 21, the frame will be positioned ver tically and the carbon strips will be held taut across the printin line, the parts being retained in this position by reason of the engagement of the roller 174 with the shallow retaining seat 176 of the cam 161. .It will be recalled that each forward movement of the frame X from its normal inclined position to the vertical is attended by a rearward movement of the platen away from tight compacting engagement with the work sheets and carbon strips, and that when the frame is vertical the work sheets will therefore be disposed loose and substantially vertical and flat in front of the platen.

After the frame has reached the vertical, the continued movement of the lever 165 toward the right will cause the roller 17 4 to riage, all of the operations which are inde# pendently effected b 1 the lever taking place during the single hand engagement with such lever that is customarily employed to return the carriage in the ordinary machine.

During the line spacing and carbon strip feed effecting movement of the lever 165 the frame is retainedin the-vertical position since the roller 180 will ride on the concentric surface 183 of the cam 161.

`It should be understood that the carbon strips are fed a short distance only at-each feeding interval, for example one-sixteenth of an inch. This feed distance may be varied by use of the devices 147,148, 149, and when the carbon strips finally pass out between the feed rollers 119, and 120 they are exhausted and may be torn off. and thrown away.

Carbon strips of this character sufficient to write a very large number of forms may be mounted in either of the forms shown in a very compact condition. lIn the preferred form they are carried by the machine frame (see Figures 1 and 3) and therefore they do not impose any added weight or resistance ,t0 the movement of the carriage. Even when carried by the carriage they add a relatively small amount of weight and do not interfere with the easy operation of the machine.'

As each -line of, the form being written `is completed, the lever movement above described is repeated to effect line spacing, ribbon feed and carriage return.

When the form has been completed the truck Y will have reached an elevated position, such as is shown in Figure 6. Thelever 165 is then moved to the position shown in Figures'9 and 21 to bring the frame vX to thevvertical position and to impose the additional tension upon the carbon strips to hold them taut in their interleaved relation with the now loose and substantially fla-t work sheets.

Proper actuation of thelever 41 will Arelease the cla-mpy 36 from the work sheets and also release the pawls of the line spacing mechanism from engagement with the toothed parts 42 and 48 with which they cooperate whereupon the truck Y may be moved downwardly to its lowest position, during which movement the leading end of the workl sheets will be held by hand. l f

The completed form is then pulled upwardly through the truck clamp a sniieient distance to bring the bottom thereof into register with the clamp bar 36. The clamp bar 36 is then caused to press tightly against the line separating the completed form from the vform next succeeding so that said bar can -be used as a tearing edge to facilitate the removal of the completed form. Upon return of the lever 165 to its normal position the frame X and the Ycarriage will likewise be returned to their normal positions and the machine parts will then be in` position to begin writing on the next form, no additional manipulation being necessary to .bring the car-A bon strips into proper relation with the work vsheets or platen.

It will be understood that eachtime the work sheets are line spaced or otherwise moved, the frame X is first moved to the ver-` tical position to relieve the normal curved and compacted condition of the work sheets and interleaved carbon strips at the printing line, and to dispose the work sheets in a loose, vertical and flat condition to enable the line spacing movement of the work sheets, as well as the carbon strip feed movement, to take place without danger of the carbon strips being dragged upwardly and out of position by the work sheets or the work sheets smutted .or smeared by tight frictional engagement with said carbon strips.

There may be combined with the invention thus far described a separate record work sheet for use in what is frequently known as condensed billing. This work sheet L will be fed around the platen through a separate chute 186 so that adjustment of the continuous work sheets may be obtained without displacement of the record-sheet.

This sheet is generally wider than the continuous sheets and contains information which is not printed upon the continuous sheets. The printing on the record sheetoutside the margins of the continuous sheets will be directly through the carbon strips so in the usual manner, the first line of writ-'g ing thereon will be recorded on the record sheet on the very neXt line from the last line of the previously written bill. A condensed record is, therefore, obtained. When the record sheet is filled, a second sheet can be inserted in the usual manner after the first is removed by releasing the clamp therefrom. p v

Various features of the invention are broader than the specific form illustrated. Instead of returning the carriage and performing the other operations by a manually operated lever, the' same might be operated by power mechanism. Also while the specific form of carbon strip feeding mechanism is illustrated as a pair of corrugated rolls between which all strips pass, it would, of course, be possible to provide a separate' pair of feeding rolls for each carbon strip, in which case smooth feeding rolls would be satisfactory.

in the way of ease and efficiency of operation, and the economies effected by savings in labor and materials incident to such operation, some of which advantages are enumerated below and other of which will be obvious to those skilled in the art.

The substitution of carbon strips or ribbons for the customary carbon paper sheets and the use of a vertically-travelling paper truck which pulls the forms up past the printing line bring about obvious advantages. The include the complete elimination of car on handling for from 1000 ,to 5000 forms, depending upon how many are included in a pack-an economy amounting to anywhere from 30 to 50% in carbon paper cost--perfect lateral and vertical registration of forms,and considerable saving of time in the writing of bills or forms over previously known methods.

The machine is capable of making good, clear, legible carbon copies automatically at all times-whether it is the first or the thousandth form written-without any effort or attention on the part of the operator. Eve carbon copy written will be clear and legibe and no mistakes willv occur due to poor legibility.

The machine herein described feeds both the form andA the carbon automatically. When the operator has torn ofiI the form just written, the next new form is at the first writing line and absolutely no time or effort is expended on fussing with carbon paper sheets. With the usual preparatory work thus done away with, the writing of any form is reduced to an ordinary typing opera-tion. v

With every actuation of the line space handle the carbon strips are fed acrossl the printing line a fixed distance, say from -Ilgth of an inch to ths of an inch depending on the feed adjustment. Therefore, any spot on the Acarbon strips will be called upon to make as many impressions as {@th of an inch lor ths of an inch will divide into the width of the form used.

The automatic feed of the carbon strips relieves the operator of the continual mental effort of deciding whether another set of .forms can be written or not with the car- 4bon sheets just used without getting into difficulties in one or two ways; that of throwing the carbon paper away before it is entirel used up and being wasteful, or of using 1t too long and allowing the work to become illegible.

For the best carbon copies, it is necessary to have all the parts of the form and the several carbon strips .in as ciose a pack as possible at the writing point, so that the force of the 1blow of the type bar will carry through to the last copy with a iight staccato blow.` This is not possible with ordinary typewriter construction, becauseA there must be room between the pieten and 'the writmg line for the form be fed upwardly,

otherwise the form will bind. In the machine herein described, however, when the form is fed upwardly, the platen is first backed away from the writing line giving vthe form plenty of room to be fed either upward or backward; but when the machine is ready to write, the platen and the form are actually pushed right up against the writing point, lthus compacting the superposed form sheets and interleaved carbon strips at the writing line. This construction will even iron out any air ockets that sometimes form with use of car on sheets.

' Thus by using carbon strips which are fed automatically, and by the use of an oscillating platen, the machine presents the ideal condition under which to make carbon copies without any effort or attention on the part of the operator.

The novel mechanisms employed in the machine for feeding the forms, also bring about notable advantages in the way of visibility and the assurance that the superposed forms will always remain in perfect registration.

Full view of the progress of the work is desirable in ordinary typewriting and is an absolute essential in form writing. With the typewriter 'the operator writes an unbroken line straightacross the paper and, to see if it is correct, looks only at the finished line. Writing forms, though, is an altogether different proposition. The typing here is not in an unbroken line. If it is an invoice form, there are usually a number of items to fill in very definite and particular spaces in the form. There may be definite and particular columns in .which to fill certain figures. If the operator has not her work v'isble and cannot see exactly what she is writing, she is very apt to write in the wrong place or column. Supporting the form web upon a flat frame and effecting line space movement thereof by a truck which clamps the leading edges thereof, assures perfect visibility of the whole of the written portion of a form as the form is being written.

In the use ofcontinuous or web forms it is very important to secure good registration. By this is meant the ability to write on the same relative line on each part ot' item and the last part of the form will designate an entirely different item. This will actually happen if the machine used to do the typingdoes not give good registration.

Tlieherein. described machine eliminates the cylinder and feed roll method of feed- Lseaeoa ing'and consequently is free from the dis'- advantages occasioned by variations in work thicknesses land combined platen' and work diameters and the creeping and slippage commonly dealt with in machines which employ such feeding instrumentalities. Inmy improved machine the work sheets are drawn forwardly and upwardly over the frame and past the printingline by a truck that is Jfed step-by-step through proper line space distances and which has thereon a clamp to grip the leading ends of saidsheets.v The tight clamping of the leading sheet ends and the substantially Hat travel of said sheets assures perfect registration atall times with out the aid of side clamps vor registering hooks or pins operating through necessarily perforated form sheets. 4The employment of web side clamps and other types of such registration effecting devices requires the expenditure of. additional :unnecessary labor in form typing operations, and on thisj point alone the herein-described machineI materially increases the potential output of work.

It is to be noted that various vfeatures of the invention arecapableof' use in different relations and that they are not limited in theirapplication to any specific type of machine. So far as lthe `feeding movement of the work sheets and carbon strips is concerned, it is entirely immaterial whether the carriage has letter space movement or whether type mechanism is movable relatively to said work sheets. This portion of the in'- vention might also be used in vmanifolding apparatus in which the writing is performed manually. It is also to be noted that various vfeatures of the invention may bemodiied widely and thatt-he present construction is to be regarded as lillustrative and not as limiting the scope'of the invention.
